Remove node ​

interactionsgraph-drawing

This example shows how to remove a node from the graph using the removeNode method.

ts
import Ogma from '@linkurious/ogma';

const ogma = new Ogma({
  container: 'graph-container'
});

ogma.generate
  .grid({
    rows: 3,
    columns: 3
  })
  .then(graph => ogma.setGraph(graph))
  .then(() => ogma.view.locateGraph())
  .then(() => {
    // Remove the node after 1s
    setTimeout(() => {
      ogma.removeNode(5);
      // notice that the adjacent edges are also removed
    }, 1000);

    // Notice that removeNodes(array) is a faster operation
    // to remove multiple nodes at once.
  });
